WILLIAM C. WALTER, OF PHILADELPHIA, PENNSYLVANIA.

PRINTING-SURFACE.

SPECIFICATION forming part of Letters Patent No. 232,786, dated September 28, 1880.

Application filed March 23, 1880. (ModeL) To all whom it may concern:

Be it known that I, W. CHARLES WALTER, a citizen of the United States, residing in the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Means for Printing Wall and other Paper, which improvement is fully set forth in the following specification and accompanying drawingsfln which- Figure 1 is aside view of a roller or block embodying my invention. Fig. 2 is a face view thereof.

Similar letters of reference indicate correspondin g parts in the several figures.

My invention consists in forming designs from which wall and other ornamental or fig-- nred paper is printed on rollers or blocks, the shading and ground whereof are produced by different grades of sand, powdered rock, or similar substances, which are properly glued or cemented to the rollers or block, and form printingsurfaces for said shading and ground.

Referring to the drawings, A represents a roller or block, on the face of which are formed or secured the designs a a, which are properly produced from composition, paper, 860., fixed to said face.

B represents sand, powdered rock, or other gritty substance, which is glued, cemented, 850., to the face of the roller or block A, and

afterward ground to form a smooth surface from which to print the ground or shading of the design.

In applying the sand it is required to exercise proper judgment for forming shading, shadows, 850., within the confines of each of the designs a, or between different parts of the designs.

Sand of different grades is employed to form light and heavy (lots, and laid thickly or sparsely, in order to produce the best effects of light and shade and complete the print.

The number of rollers or blocks employed is equal to the number of colors to be printed.

The designs a a are readily produced and applied to the roller or block A, and when Worn away may be replaced, and the sand may also be renewed when required.

Having thus described my invention, what 1 claim as new, and desire to secure by Letters Patent, is-

A printing surface which consists of sand or particles of similar substances applied to the roller or block A, substantially as and for the purpose set forth.

W. CHAS. WALTER.
